This analysis comprises the whole population (n=567), where quartiles are defined for lapses (Q1: 0–4 lapses; Q4: over 35 lapses) and Sample Entropy (Q1: 0–0.12; Q4: over 0.71) separately. Both models are computed using the logit-link function. Models were constructed using constant starting model, Bayesian Information Criterion (BIC) as a model entering criterion and treating the response variable as a categorical variable. All models were constructed by separately inputting investigated polysomnography-based parameters. Parameters that were excluded from the final regression model based on BIC are left blank. BMI: body mass index; COPD: chronic obstructive pulmonary disease; ESS: Epworth Sleepiness Scale; AHI: apnoea–hypopnoea index; t_{90%}: time spent under 90% saturation; AI: arousal index; N1–N3: non-rapid eye movement sleep stages 1–3; REM: rapid eye movement sleep; APF: arterial pulsation frequency.
